Abstract (en)
[origin: WO2014004598A2] The invention relates to a process for multilayer coating of substrates comprising the steps: 1. applying a base coat layer of a water-based colour- and/or special effect-imparting base coat composition onto an optionally pre-coated substrate, 2. applying a clear coat layer of a transparent clear coat composition onto the base coat layer and 3. curing the clear coat layer applied in step 3, wherein the water-based colour- and/or special effect-imparting base coat composition comprises: A) at least one water-dilutable polyurethane hybrid binder, obtained by polymerization of at least one polyurethane macromonomer, containing at least one lateral and/or terminal vinyl group, in the presence of at least one unsaturated monomer copolymerizable with the polyurethane macromonomer, B) optionally at least one curing agent, and C) at least one pigment, wherein the at least one polyurethane macromonomer is based on at least one polyhydroxyl compound, said polyhydroxyl compound comprises at least 50 % by weight of at least one polycarbonate polyol, which is liquid at 20C, the % by weight are based on the total amount of the polyhydroxyl compound.
